Caricatures are more effective than police sketches

British researchers are recommending that cops drop the practice of circulating police sketches of suspects in favor of crazy, amusement-pier-style caricatures that "over-emphasise prominent features."
A study at the University of Central Lancashire found that over-emphasising prominent features on people's faces made them twice as easy to identify than before.

The researchers used computer software to alter the faces of 18 celebrities which had been created using three standard photofit techniques. The faces were then turned into caricatures by exaggerating certain features, such as the size of a person's ears, forehead or nose, by as much as 50%.
